M6 x 13mm Pin for Filament Drive Idler Arm

I printed the filament drive found here: http://www.thingiverse.com/thing:7113, but I found myself lacking an M6 bolt + nut.

Because the bearing just needs to be held in there, but not tightened down, I decided to design a pin to do the job. This pin is 19mm long, with 3mm of base, and 3mm for the flange at the end. The base will sit ~1mm from the back of the filament drive when it is engaged, so the pin is incapable of coming out while in use.
